Unit Explanations
MillihenrymH
Source UnitThe millihenry (mH) is a derived unit of inductance in the International System of Units (SI), representing one thousandth of a henry (H). It quantifies the ability of a conductor to induce electromotive force (EMF) when the current flowing through it changes. Inductance is a fundamental property in electrical engineering and physics, underlying the principles of electromagnetism. The relationship between inductance and magnetic flux linkage is critical in the design of electrical circuits, transformers, and inductors. The millihenry is widely used in various applications where smaller inductance values are required, making it an essential unit in electronics and electrical engineering.
Current Use
The millihenry is widely utilized in various industries, particularly in electronics, telecommunications, and automotive engineering. In circuit design, millihenries are often employed to specify the inductance of inductors and transformers, particularly in applications requiring compact components with precise inductive values. Electronics manufacturers, engineers, and hobbyists rely on millihenries for designing filters, oscillators, and power supplies. Countries such as the United States, Japan, Germany, and South Korea prominently use this unit in educational settings, research, and practical applications. The rise of portable electronics and high-frequency applications has further solidified the importance of millihenries in modern electrical engineering.
Fun Fact
The henry, the base unit of inductance, is named after Joseph Henry, who also discovered self-induction.
Electromagnetic System Unit of Inductanceesu
Target UnitThe electromagnetic system unit of inductance (esu) is a derived unit in the centimeter-gram-second (CGS) system of electromagnetic units. It quantifies the inductance of a circuit, which is the property that allows it to store energy in a magnetic field when electric current flows through it. One esu of inductance is defined as the inductance that induces an electromotive force of one electrostatic unit (esu) when the current changes at the rate of one esu per second. This unit is particularly significant in the context of electromagnetic theory and applications where the interaction of electric and magnetic fields is crucial. The esu is foundational in the study of electromagnetism, serving as a bridge between electricity and magnetism, capturing the essence of inductive behavior in circuits.
Current Use
The esu of inductance is primarily used in theoretical physics and electromagnetic studies, particularly in the context of the CGS system. While the SI unit of inductance, the henry (H), is more commonly used in practical applications, the esu remains relevant in specific academic and scientific discussions. In fields such as plasma physics, astrophysics, and certain branches of electrical engineering, the esu serves as a reference point for understanding inductive behavior. Countries utilizing the esu include those engaged in advanced physics research, particularly within academic institutions that focus on classical electromagnetism. Its applications can be seen in simulations and theoretical models where traditional CGS units are preferred for historical continuity and pedagogical clarity.
Fun Fact
The esu of inductance is rarely encountered in everyday applications but remains pivotal in theoretical discussions.

Definition
The millihenry (mH) is a derived unit of inductance in the International System of Units (SI), representing one thousandth of a henry (H). It quantifies the ability of a conductor to induce electromotive force (EMF) when the current flowing through it changes. Inductance is a fundamental property in electrical engineering and physics, underlying the principles of electromagnetism. The relationship between inductance and magnetic flux linkage is critical in the design of electrical circuits, transformers, and inductors. The millihenry is widely used in various applications where smaller inductance values are required, making it an essential unit in electronics and electrical engineering.
History & Origin
The concept of inductance, and consequently units like the henry and its submultiples, emerged from the work of several physicists in the 19th century. Particularly, Joseph Henry, an American scientist, played a pivotal role in the discovery of self-induction and mutual induction. His experiments demonstrated how a change in current in a coil could induce an electromotive force in the same coil or in a nearby coil. This foundational work laid the groundwork for electromagnetic theory and the development of inductive components. The millihenry, as a practical subunit, became widely adopted as electronic components grew smaller and more complex, facilitating its use in modern circuit design.
Etymology: The term 'millihenry' derives from the prefix 'milli-', meaning one thousandth, combined with 'henry', named after Joseph Henry.
